DAVID: We don't know how far epigenetic changes can/will make new species, since we don't know how new species are created. We've had this discussion before about inventive mechanisms, with no conclusion except there might exist like it.

dhw: That is what I call progress. I have fought long and hard for the concession that this hypothesis is possible! Since none of the facts are known, only the faithful can draw clear conclusions.

I don't view it as progress, because we had a long discussion in which both of us discussed the possibility. Certainly a possibility as we keep opening up layers of DNA control and expression, there might be a speciation layer pre-programmed to allow for giant leaps in phenotypes.
